After filling Leno in on where Part 2 picks up (c'mon Jay!), the late-night talk show host says, "But there's a twist, because the ending—I don't wanna give anything away—is a little different from maybe, what was in the book."

"You know," Taylor responds, "There's a very thin line because the fans would freak on us if we changed anything too much."

So what can he tell us?!

"I can confirm there is a twist and I can confirm everybody can find out what it is on Nov. 16."
